Pre‐mining depressurizing of a deep ore body at the McArthur River mine, the largest single producer of uranium in the world, was considered to decrease the risk associated with mining and increase the ground stability and the amount of ore that could be extracted. The challenge was to depressurize the high‐grade ore bodies without propagating a significant amount of drawdown to the surface where impacts on surface‐water resources and the associated aquatic habitat would be significant environmental issues. The objective was to evaluate the technical and economic feasibility of depressurizing the ore body.

Itasca is pleased to announce that the 6th Itasca Symposium on Applied Numerical Modeling will take place June 3 - 6, 2024, in Toronto, Canada.
Miguel Fuenzalida (M.A.Sc., B.Eng.) is a Principal Geomechanics Engineer at Itasca Consulting Group, a consulting and software firm across the mining, civil engineering, and energy industries. He holds a Bachelor’s degree and a Master of Science in Mining Engineering from the University of Chile. He has received the “Juan Bruggen” Best Graduate of the Class of 2010 Mining Engineering Award by the Mining Engineering Institute of Chile (IIMCh). Based in Minneapolis, USA, Miguel provides consulting services to underground mining by applying numerical modeling to sequencing, stability, ground support, and mining-induced seismicity. Miguel has extensive experience in sublevel, block and panel caving projects—from concept to feasibility level—and cave mines in North America, South America, Africa, Eastern Europe, Southeast Asia, and Australia where he has specialized in undercut and extraction level design, draw scheduling, forecasting of caveability, fragmentation, recovery, infrastructure stability, and surface subsidence. He has participated in several mining and rock mechanics conferences and has been part of international collaborative research consortiums such as Mass Mining Technology (MMT) and Caving2040, focused on critical reviews of conventional caving design approaches, collation of common caving practices, and advancing the understanding of caving fundamentals. He is currently a member of the American Rock Mechanics Association (ARMA) and the Society of Mining Engineering (SME).
